Like this, test unit just can carry out the scale removal operation to isolation switch contact earlier in clamping process, give control circuit by the hand-held remote controller sending controling instruction, control circuit starts, and trigger and control the micromachine startup, the minitype motor driving gear part rotates, when gear part rotates, the projection of sawtooth row front end moves with gear rotation trend crown direction and realizes moving backward, thereby drive sawtooth discharged to the back motion, and under the effect of back-moving spring, realize pretension, rotate when entering teeth groove homing forward at projection with gear, thereby under the effect of gear part and back-moving spring, this sawtooth row move back and forth, and the sawtooth on the sawtooth row is removed the dust and dirt on the isolation switch contact at the volley, surface film oxide or surface lacquer.Like this, test unit can make it more good with contacting of contact after scale removal, thereby has guaranteed the reliability of test figure.
Last clamp device also includes a plurality of damping springs, and it is installed in sawtooth row's upper end.
Damping spring comes scale removal for sawtooth and eliminates vibrations as much as possible, with protection sawtooth row.
Control circuit includes wireless remote control receiver module, controller module and motor drive module, wireless remote control receiver module, controller module and motor drive module are electrically connected in turn, and the wireless remote control receiver module can receive the wireless control signal of hand-held remote controller.
The wireless remote control receiver module receives the wireless control signal of hand-held remote controller, and exports to controller module, and controller module output control signal is given motor drive module, by the motor drive module drive motor.Hand-held remote controller and control circuit can adopt conventional commercially available telepilot and controller.
In sum, the utility model provides a kind of high voltage isolator based on remote control auxiliary checking experiment device, adopted the distance type operation, the operating personnel need not to carry out work high above the ground again, only need by sufficiently long insulating bar test unit to be placed on the switch contact, therefore ensured personal safety; In addition, the folder mouth of this test unit can be accomplished enough big, goes for isolation switch contact of all sizes, realizes clamping operation preferably, and is simple to operation, shortened the activity duration, reduced operating personnel's workload.
